Hi! Great question. Our team has thought long and hard about this, and we think the best option would be to make a 3oz bottle and save the extra in the refrigerator. Due to the size of our scoop, it’s tricky to make sure baby will get the exact ratios (and nutrition!) if you try to do a 2 1/2 oz bottle. Let us know if you have any other questions!

That's interesting, on the can it says to discard within one hour. So can we save unused milk or no?  My daughter has wasted many ounces in total 😩
